Tests overseen by ArianeGroup at the DLR German Aerospace Center’s Lampoldshausen testing facility in Germany in 2020 will validate the hardware components for the first Prometheus engine test model (M1).
In preparation, the P5 test bench will gain a 250 cubic metre capacity propellant tank for methane. This will allow engineers to efficiently switch test configurations between Prometheus and Ariane 6’s Vulcain 2.1 main stage engine, also in development.
